Abstract
The application relates to the technical field of display, and provides an anti-dazzle liquid as well as a preparation method and an application thereof, wherein the anti-dazzle liquid comprises the following components in percentage by weight: 40-60 parts of UV curing liquid; 0.5 to 2 parts of first organic particles; 0.5 to 2 parts of second organic particles; 35-55 parts of an organic solvent; 0.03-0.5 part of an auxiliary agent; wherein the particle size of the first organic particles is 3-5 micrometers, and the particle size of the second organic particles is 0.5-2.5 micrometers. By controlling the particle size of the two organic particles, on one hand, the particle dispersion is facilitated, so that a smaller uneven plane is formed on the whole coating, and the obtained anti-dazzle film can obtain larger haze and has no whitening condition; on the other hand, the light transmittance of the film is not reduced even if the thickness of the antiglare layer is increased appropriately, and high hardness and excellent abrasion resistance are ensured.
Description

Background
In recent years, flat panel display (OLED, LCD, PDP) technology and related products have been rapidly developed. The outer surface of the display reflects ambient natural light or internally generated strong light, causing eye fatigue or headache and blurring vision of an image formed in the display. In order to prevent reflection of an external scene on a display surface of a liquid crystal display device or the like, a mixture of fine particles and a binder resin or a curable resin is generally applied to TAC of an upper polarizer in a liquid crystal display, and fine irregularities are formed on the surface to prevent regular reflection, thereby exhibiting anti-glare properties.
In the existing technology for manufacturing the anti-glare film, a higher haze value causes greater diffusion of external light, which makes the anti-glare effect better, but also causes image distortion due to surface scattering of light and whitening phenomenon due to internal scattering of light, thereby deteriorating contrast. Some of the prepared anti-glare layers have a thickness of about 0.5 times the particle size of the anti-glare particles, resulting in whitening of the entire coating and a decrease in contrast; while the other part of the antiglare film reduces glare by increasing the haze value, a film obtained by decreasing the thickness of the antiglare layer has a haze of 10% or more, on the one hand, high antiglare properties, but on the other hand, the coating film is whitish. There is a problem that visibility of displayed characters is lowered, and the antiglare layer having irregularities is likely to be cracked by stretching during thermoforming. Still another part of the prepared antiglare hard coat film needs to reduce light scattering property to reduce haze in order to improve visibility, and thus there is a tendency that antiglare property is reduced, that is, antiglare property and visibility are in a trade-off relationship, resulting in the antiglare film formed at present or the coating layer is whitened; or low haze, can interfere with normal use.

The anti-dazzle film comprises a transparent substrate film and an anti-dazzle liquid film layer arranged on any surface of the transparent substrate film; wherein the transparent substrate film is selected from cellulose triacetate film with the thickness of 80 microns; the anti-glare liquid is the anti-glare liquid provided in comparative example 3, and the thickness of the obtained anti-glare liquid film layer is 3 micrometers.
The preparation method of the anti-dazzle film comprises the following steps: the antiglare liquid prepared above was coated on a cellulose triacetate film (Fuji) having a thickness of 80 μm by means of a micro gravure coating method, and after the formed coating layer was dried in an oven at 60 ℃ for about 1min, it was passed through ultraviolet raysIrradiating to cure the coating, wherein the curing energy is 350mj/cm2And forming an anti-dazzle liquid film layer with the thickness of 3 microns to obtain the anti-dazzle film.
And (3) performance testing:
the antiglare films obtained in examples 1 to 3 and comparative examples 1 to 3 were subjected to the following performance tests:
1. thickness of coating film
A small piece (2 mm. times.300 mm) of the sample with the antiglare liquid film layer was taken and the thickness of the antiglare layer was measured by observing the cross section thereof under an optical microscope.
2. Haze degree
Measured by the transmitted light method using a Japanese electrochromic NDH 2000N type haze meter in accordance with JIS K-7105.
3. Hardness of pencil
The pencil hardness of the product was measured in accordance with JIS K-5600. Measurement method: using a Mitsubishi pencil with the hardness of H-3H, drawing 5 lines under a load of 750g, observing whether the hardened film coating is scratched or not, and judging according to the following standards:
judging 'OK' when 0-1 scratch is made;
and judging NG (NG) after 2-5 scratches are formed.
4. Steel wool scratch resistance
The hard coat layer was rubbed back and forth 10 times with #0000 steel wool under a load of 500gf/cm2 using a abrasion tester to confirm whether the coating layer was scratched or not. And the determination is made according to the following criteria:
0 scratch is judged as 'OK';
and (5) judging NG (if the scratch is not less than 1).
5. The whitening of the coating film by transmitted light was evaluated as follows: when a white fluorescent lamp was observed through the antiglare hard coat film with the coated surface facing the observer side, the state of light diffusion in the film and whitening of the coating film due to internal haze was visually evaluated. The case where the film was not whitened and was less whitened was evaluated as "o", the case where the film was slightly whitened was evaluated as "Δ", and the case where the film was whitened was evaluated as "x".
And (4) analyzing results:
the performance test of the antiglare films obtained in examples 1 to 3 and comparative examples 1 to 3 showed the following results, as shown in table 1: in the embodiments 1 to 3, two different organic particles are selected, and the thickness of the anti-dazzle hard coating is controlled to be 1.3 to 1.8 times of the average particle size of the first organic particle, so that the prepared anti-dazzle hard coating film has intermediate haze and no whitening phenomenon on the surface of the film, the surface has an oil sand granular feel, the wear resistance is excellent, the hardness is not less than 3H, the total light transmittance is greater than 90%, and the haze is set to be 5 to 15%. In addition, in comparative example 1, in which monodisperse organic fine particles having an average particle diameter of 3.5 μm were selected, the antiglare hard coat film particles were easily agglomerated, and more particles were exposed on the surface, which gave a stronger granular feel, poor appearance, and whitening of the surface. The average particle size of the first organic particles in comparative example 2 was decreased, the coating film was not whitened, but the haze was too low, and the antiglare property was not good enough. In addition, in comparative example 3, the thickness of the coating layer was smaller than the average particle diameter of the first organic particles, resulting in a corresponding decrease in hardness of the coating film, while its haze was increased and the surface was severely whitened.
In summary, the anti-glare liquid provided by the application uses the UV curing liquid as a main component, and the first organic particles and the second organic particles are cooperatively matched, wherein the particle size of the first organic particles is 3-5 micrometers, and the particle size of the second organic particles is 0.5-2.5 micrometers. By controlling the particle size of the two organic particles, on one hand, the dispersion of the particles is facilitated, the thickness of the obtained anti-dazzle layer is controlled to obtain anti-dazzle performance more than necessary, so that more particles with small particle size are arranged in the coating, and particles with large particle size are raised on the coating, so that the whole coating forms a smaller uneven plane, and the obtained anti-dazzle film can obtain larger haze and the anti-dazzle layer is free from whitening; on the other hand, providing two types of particles having different particle diameters ensures high hardness and excellent wear resistance without lowering the light transmittance of the film even if the thickness of the antiglare layer is appropriately increased. The obtained anti-dazzle liquid can ensure that the surface of the obtained anti-dazzle film has an oil sand granular feeling in the using process, has good anti-dazzle performance, can reduce the phenomenon of poor scratch in the process of assembling a display screen, and is suitable for wide application. The anti-dazzle liquid can obtain higher haze and the anti-dazzle layer does not have whitening, so that the obtained anti-dazzle film has intermediate haze, no whitening phenomenon on the surface of the film, high surface hardness and excellent wear resistance.
